A leading international architectural practice has installed Eco Cistem at its headquarters in London.

Eco Cistem Director, Graham Kelly, said: “This international architect has an unquestionable pedigree designing some of the world’s greenest buildings.

“By installing Eco Cistem in its headquarters, a huge amount of water will be saved every year.

“Data from a recent office installation showed Eco Cistem reduced the amount of water used to flush the toilet by over 75 per cent.

“And for the first time for a cistern, architects could claim two extra BREEAM credits and as many as five when Eco Cistem is used with other water saving devices.

“Up to six LEED points could also be achieved.”

Eco Cistem is the world’s only cistern to use condensate from air conditioning units to flush the toilet.

In doing so it virtually eliminates the need to use mains water.
